. To all whom it may concern:

new and useful Improvements in Oil Va porizers and Mixers, of which thefollowing is a specification.

This invention relates to improvements in carbureters or generators andhas particular application to devices of the character above set forthfor vaporizing volatile fluids, such, for instance, as petroleum and itsby-prodnets, and mixing the same with air to produce a hydrocarbon gas.

In carrying out the present invention, it is my purpose to provide agenerator or carbureter wherein the volatile liquids and air may beheated so as to vaporize the former and enable the free commingling ofthe resultant vapor with the air, thus producing a gas capable ofexplosion, which gas may be led into the cylinders of an ex plosiveengine or utilized for other purposes as desired.

It is also my purpose to provide a device of the character above setforth wherein the quantities of vapor and air may be regu-' latedindependently of each other previous to the mixing operation and whereinquantities'of such air and vapor may be regulated and controlledsimultaneously.

With the above and other objects in View, the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthin and falling within the scope of the claim.

In the accompanying drawings: Figure 1 is a side elevation of acarbureter or gen erator constructed in accordance with the presentinvention. Fig. 2 is a vertical central sectional view of the same,parts being shown in elevation.

Referring now to the accompanying drawings in detail, A indicates thecasing or body of the device which, in the present instance, is providedwith a removable cover 2 threaded onto the body or fastened thereto inany suitable manner, a bracket 3 or the like being employed so that thedevice may be attached to a suitable or convenient object or support.Mounted within the casing A and secured thereto by means of brackets 4secured to the walls'of the casing at diametricallyopposite points, areburners 5,

preferably of the retort type'and each including a conduit 6, a retort7, and a burner section 8, suitable couplings being employed to connectthe retort to the conduit and the burner to the retort, the conduits 6of the burners being connected up to a suitable source of supply, as afuel reservoir 9.

Leading into the casing A is a fuel pipe 10 terminating withlt thecasing in branch portions 11, 11 leading around the burners andconnected to each other by means of a vaporizing tube 12 arranged acrossthe top of the burners and parallel therewith so as to attain themaximum head therefrom, the pipe 10 being connected up to a suitablereservoir 13 containing a volatile liquid, such as petroleum or itsby-products and connected up to a pump 14 so 'that such liquid may beforced, under pressure, into the vaporizing tube 12.

Arranged within the casing A preferably above the vaporizing tube 12 andwithin the heat zone of the burners, are air receivers 15, 15 each inopen communication with an air conduit 16 terminating in a common main17 connected up to a source of supply, as an air reservoir 18 receivingair from the compressor 19. v The ai receivers 15, 15

are preferably spaced apart, as shown in Fig. 2, and secured to thevaporizing tube 12 and'supported thereupon by means of the brackets 20,and the vaporizing tube 12, at a point approximately centrally of thedistance between the air receivers 15, 15, is

' provided with an outlet nipple 21 in which is arranged an outwardlyopening check valve 22, and connected to which is an expansible vaporreceiver 23 designed to receive the vapor from the vaporizing tube 12and adapted to hold such vapor until the same is utilized, the checkvalve 22 opening to permit the flow of the gaseous vapor or fluid fromthe vaporizing tube 12, but preventing back flow of such fluid from thereceiver. This receiver is preferably in the form of a collapsible bag,asshown, and to the upper extremity thereof is connected a. valve casing24 in which is arranged a- 1'0 tary plug valve or the like 25 designedto control the flow of gas from the bag and adapted to cut off suchflow. Leading from each air receiver 15, is a right angular outletnipple 26 to the free extremity of which is fastened in any suitablemanner a valve casing 27 in which is rotatably mounted a till pocketadapted plug valve or the like Qdadapted to. control theflow of air fromthe respective reservoir and cut ofi such flow.

Arranged within the casing A and projecting outwardly thereof through anaperture 29 in the cover 2, is a mixing tube 30 su'pported or heldWithin the casing in any suitable manner, as by the suspension bracket31. To the lower end'of the mixing tube 30 within the casing A, is screwthreaded or otherwise fastened a coupling InemberZ-KQ having afrusto-conical shaped bottom 33 formed in its raised portion with aplurality of threaded apertures 34 depending from which and threadedthereinto are spray nozzles casings of the air receivers and vaporreceiver. The inclined portion of the bottom 33 of the coupling 32 andthe proximate wall of such coupling form an annular to receive sedimentor other foreign matter which might find its Way into the mixing tube.

The valves 28 and 25 are each equipped with an operating lever 36 andcommon to all of such levers is a main actuating rod 37 provided with aplurality of apertures 38 to any one of which the levers 36 may be fastened, thus enabling the valves to be adjustedindependently of oneanother so that the desired quantity of gas and air may be fed to themixing tube irrespective of each other.

From the foregoing description taken in connection with the accompanyingdrawings, the construction, mode of operation and manner of employing myinvention will be readily apparent to those skilled in the art.

The burners 8 are ignited, and the volatile liquid admitted to the pipe11 and the vaporizing tube 12, and the latter being disposed with n heheat zone of the burnconnected to the valve ers, quickly andefi'ectively vaporizes the liquid and causes such vapor to enter the gasreceiver 23. Similarly, air is admitted to the conduits 16 thence to thereservoirs 15 and owing to the proximity of the reservoirs to theburners, such air is heated. The actuating rod 3? of the valves may nowbe operated to establish communication between the gas and air receiversand the mixing tube, thereby permitting the gas an air to flow into themixing tube and freely commingle with each other. the mixing tube, theresultant explosive gas may be conducted to any suitable point ofconsun'iption, as, for instance, the cylinders of an explosive engine orother like apparatus.

While I have herein shown and described one particular form of myinvention by way of illustration, it is to be understood that I do notlimit or confine myself to the exact details of construction hereindescribed and delineated, as modification and variation may be madewithin the scope of the claim and without departing from the spirit ofthe invention.

I claim:

In a generator, a gas receiver, an air receiver, and a mixing tubecommon to said receivers, a coupling member interposed between saidreceivers and mixing tube and provided with a frusto-conical shaped bottom, the inclined portion of the bottom of the coupling and the adjacentwall of said coupling forming an annular pocket adapted to receivesediment or the like.

In testimony whereof I- ailix my signas0 ture in presence of twowitnesses.
